@Miles_Brundage @jasminewsun which PI/china analysis thing? I couldn't find it and neither could Claude...

Super cool work by @YijieIsabelLiu using RL to find shortcuts for robotic planners:

[Isabel Liu @YijieIsabelLiu]

Robots can plan, but rarely improvise. How do we move beyond pick-and-place to multi-object, improvisational manipulation without giving up completeness guarantees?

We introduce Shortcut Learning for Abstract Planning (SLAP), a new method that uses reinforcement learning (RL) to discover shortcuts in the planning graphs induced by task and motion planning (TAMP) skill libraries. It is a plug-and-play module that can be trained on top of existing planners to speed up execution through learned shortcuts.

🚨New paper at #NeurIPS2024! We present Hydra, a mixture of neural fields 🐉🐉🐉 for ab initio cryo-EM reconstruction of complex mixtures.

Hydra is our attempt at pushing the boundaries for even more extreme forms of heterogeneity in cryo-EM 🤯.

This was joint work with an awesome team, led by @axlevy0 @rishwanth_raghu & David Shustin.

Poster session happening now! Come by 👋

@SOPHONTSIMP @owl_posting It’s a figure from the CryoDRGN2 paper comparing simulated (synthetic) images through a cryo-electron microscope to images from a real cryo-electron microscope. https://t.co/VfhiKZVcCP

(1/2) Tired of your panoramas being turned into sad flat rectangles? Our latest #SIGGRAPHAsia2024 work "Neural Light Spheres" lets you turn panoramic captures into dynamic wide FOV renders (with real-time rendering!).

Had the pleasure of building an efficient Triton kernel to help scale @ArdaGoreci Ligo's open-source AlphaFold3 model!

A new component in AlphaFold3 is the MSA pair weighted averaging algo -- our Triton implementation is 3x faster with 10x less peak memory usage! (1/3)

[Axel Levy @axlevy0]

We present DRGN-AI for fast, ab initio cryo-EM reconstruction!
* learns a neural field from unposed images,
* designed for single-shot reconstruction of unfiltered datasets,
* finds new states missed by prior approaches!

Teamwork led by @ZhongingAlong

Are you interested in neural fields and computational photography? Or just really like splines and have no one to talk to about splines? Come chat with me @CVPR2024 next week on our latest spliney neural fieldy burst photography project:

[Michael Tang @_michaeltang_]

New coding benchmark! We introduce the USACO benchmark (https://t.co/RIV4tvyLLP), which tests the limits of LLM intelligence in creative, grounded, algorithmic scenarios. Key takeaways below 👇

[Felix Heide @_FelixHeide_]

Code for Neural Spline Fields is out! We use burst image fusion to see through occlusions and remove reflections.

We just released the code here: https://t.co/frpg3ex38K

Comes with a fun set of notebooks and tutorials!

[Felix Heide @_FelixHeide_]

Splines instead of Gaussians 😉 Introducing Neural Spline Fields, which can see through occlusions!

We learn to represent a stack of misaligned captures as a multi-layer image sandwich. Then you can extract your favorite layer to remove occlusions, reflections, or even your own shadows from the scene!

Fun work by @_ilya_c , @DavidShustin , @RuyuYan00, and Chenyang Lei.

1/ For the past year, we’ve been building a new research organization:

Speculative Technologies (@spec__tech) exists to create an abundant, wonder-filled future by unlocking powerful materials and manufacturing technologies that don’t have a home in other institutions.

[David Shustin @davidshustin]

@jerseyastro maybe the 10th LED is broken so the rest are cut off, try bridging over it with some wires on the contacts?

[David Shustin @davidshustin]

@jerseyastro do the lights dim over distance or just cut off?
also did you get it working a few months ago?

[hackMHS @hackMHS]
